About ICD-9-CM 88.56
88.56 is an ICD-9-CM procedure code for coronary arteriography using two catheters. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.
The CMS General Equivalence Mappings translate it to 12 ICD-10-PCS codes, such as B2000ZZ (Plain Radiography of Single Coronary Artery using High Osmolar Contrast), B2001ZZ (Plain Radiography of Single Coronary Artery using Low Osmolar Contrast) and B200YZZ (Plain Radiography of Single Coronary Artery using Other Contrast). All of these are approximate matches, so review the record to pick the right one.
